CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 403,461, dated May 14,1889.

Application filed March 8, 1889. Serial No. 302,560. (No model.)

To all whom, it may concern:

Be it known that I, MICHAEL D. COX, a citizen of the United States,residing at Knoxville, in the county of Knox and State of Ten-11essee,have invented certain new and useful Improvements in Car-Couplings, of which the following is a description.

My invention consists of an improved railroad-car coupler and draw-head,which con- Io stitutes a self-coupler, and which consists of the definedconstruction of parts hereinafter set forth and claimed, reference beinghad to accompanying drawings and the letters marked thereon, making apart of this speciiication; and in order to enable others to understandand operate the same I will now proceed to describe its construction andoperation, referring to the annexed drawings, in which- VIiigure l is aperspective view of a railroadcar draw-head with arrangements forcoupling attached. Fig. 2 is a transverse vertical section of the same,showing the position of coupling device when ready for coupling.

. 2 5 Fig. 3 is also a transverse vertical section of view ofcoupling-pin, with notch B, which receives spring-frame when holding pinin proper position for coupling, also showing shoulder C, which rests oncoupling-link, holding it in a horizontal position to receive the Fig. 9shows a front View of Fig. 10 shows a rear view of other coupling.coupling-pin. saine.

In order to operate this coupling, press spring-frame A back into theslot-hole in the upper part of the draw-head, place couplinglink inposition, and drop coupling-pin in the oblong square hole D, when theshoulder C will descend and rest on coupling-link, holding saine in ahorizontal position to receive the other coupling. Then on the otherdrawhead raise coupling-pin till the spring-frame catches in notch B, asshown in Fig. 2, which holds coupling-pin in position for coupling. Vhenthe two draw-heads come together, spring-frame A, as shown in Fig. 2,will be pressed back, as shown in Fig. 3, thereby relieving thecoupling-pin, which will drop into position, as seen in Fig. 3, therebycompleting the coupling.

In order to unoouple, raise coupling-pin till spring-frame A catches innotch B, which securely holds coupling-pin in the proper position forfuture coupling.

Having therefore fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

In a car-coupling, the combination of the oblong frame provided with thespring and the pin provided with the shoulder and the notch B, allsubstantially as described.

In testimony that I claiin the foregoing I have hereunto set my handthis19th day of February, 1889.
